Does Welding Spatter Warrant the Replacement of a Chain?

Does Welding Spatter Warrant the Replacement of a Chain?


Joe, a salesperson for a CMCO distributor and recent safety webinar attendee, asks: “Does welding spatter warrant the replacement of a chain?”

Peter Cooke, CMCO Training Manager and Safety Webinar presenter, answers:
Yes, weld spatter does warrant chain replacement. Weld spatter should be considered as heat damage. Because hoist chain is heat treated, any heat 410 degrees F and up could have an effect on the chain’s integrity. Weld splatter is molten metal at temperatures above 2,000 degrees. When it comes into contact with the chain, weld spatter adversely affects the heat treat properties of the link or links and the chain must be replaced.

Can hoist hooks be repaired?

Can hoist hooks be repaired?

LodestarHook During my training sessions, I am frequently asked if hoist hooks can be repaired if they are damaged or broken. OSHA and ASME regulations provide specific requirements for hoist hook repair to help answer this question.

According to OSHA 1910.179 (L)(3)(iii)(A), hook repairs by welding or reshaping are not generally recommended. If such repairs are attempted they shall be done under competent supervision and the hook shall be load tested before further use.

While OSHA 1910.179 specifically pertains to a crane with top-running girders and top-running trolleys, it states that hook repair is allowed under certain conditions.

On the other hand, ASME B-30.10 Section 10-1.3 (d) states that “attachments, such as handles, latch supports, etc. shall not be welded to a finished hook in field applications. If welding of an attachment such as these is required, it shall be done in manufacturing or fabrication prior to any required final heat treatment.”

So the question remains, can hoist hooks be repaired?

Typically hoist hooks are forgings processed from hot-rolled alloy steel blanks of medium carbon content, such as grade AISI 4140. Hooks can be used in the “as forged” condition or further enhanced by thermal processing (heat treatment). Although fatigue strength improves with heat treatment, there is a resulting loss of ductility and elongation.

A repair that involves welding or any kind of heat treatment can affect the strength and ratings of a hook and therefore is not recommended.

Keep in mind, when a hook is damaged or broken, it can be an indicator that the hoist was overloaded, in which case the entire unit should be inspected for other damages.

In addition to referencing OSHA and ANSI requirements for hook repair, we also recommend that you always contact the manufacturer before making any questionable repairs on their products.

CMCO University de Mexico

Columbus McKinnon recently opened “CMCO University” in Mexico. The facility will be used to give training to customers, channel partners, and employees. The campus is located within the Santiago Tianguistenco manufacturing plant, near the city of Toluca. It includes 80 square meters of classroom training space and 300 square meters of laboratories and workshops.

“CMCO University is 100% dedicated to delivering knowledge for the operation, installation and repair of hoist and rigging products.” said Rosangel Garcia, Training Coordinator for Latin America. She continued, “When we designed the facility, we modeled the classroom and workshop after the training facility in Tonawanda, New York, USA.”

The modifications to the classroom building and shop floor were completed in November 2012 and officially opened for internal training at that time. The first training class for Columbus McKinnon customers was held in February.

Future plans include additional training classes for customers throughout the Latin America region. The ability to provide education within the region, in the customers’ local language, is a key element in the CMCO strategy of staying close to the customer.

CMCO University

Last month Columbus McKinnon kicked off its inaugural session of CMCO University with great success. More than 15 distributor associates from across the country came to our  Niagara Training Center in Tonawanda, N.Y.,  to “Profit from Knowledge,” learning detailed information about our products and how to best sell and position them in the marketplace.

CMCO’s Niagara Training Center is one of the most comprehensive hoist, crane and rigging training centers in the country. With more than 40 hoists, including powered and manual hoists, as well as a variety of crane components and rigging products, attendees gained valuable experience operating the products. They were able to see the interior workings of the hoists, learn about their unique features and conduct hands-on product comparisons.

Testing out Products

Not only did the distributors learn about our products, they also had a chance to enjoy the unique sights and tastes of Buffalo, N.Y., including a trip to one of the Seven Wonders of the World – Niagara Falls; a visit to downtown Buffalo and First Niagara Center for a Buffalo Sabres hockey game; and various meals to experience Buffalo’s famous cuisine.

With the success of our first session, CMCO University classes are filling up fast. Keep an eye out for information on upcoming sessions – we’ll be scheduling throughout 2014.

Webinar Teaches Inspection & Maintenance of CM Hurricane 360 & Short Handle Puller

Webinar Teaches Inspection & Maintenance of CM Hurricane 360 & Short Handle Puller

Do you want to learn how to inspect our new CM Hurricane 360 chain hoist?
Peter Cooke, our Training Manager for Rigging & Load Securement, will teach you how to properly disassemble, inspect and reassemble our popular CM Hurricane 360 hand chain hoist in our free Safety Webinar.  Peter will also walk you though how to set the brake on our CM Hurricane 360 and explain how it can handle your most challenging applications.

Do you have applications that call for drifting a load, standing above a load, or working in confined spaces?
Unlike traditional hand chain hoists, the Hurricane 360 may be used in any direction due to its patented hand chain cover. It rotates 360 degrees allowing a convenient way to move loads without standing under or near the load. The hoist allows for positioning, pulling and lifting of loads from virtually any angle – making it the only hoist of its kind in the industry.

If you have dealt with these tough conditions when operating a hoist, check out our above videos and see how well the Hurricane handles the job.

Plus, Learn How to Inspect a CM Short Handle Puller
During the webinar, Peter will also cover proper inspection techniques for our CM Short Handle Puller. This hoist has a similar brake, yet requires a different approach to set it than your typical Weston type brake. This mechanism was designed for precision positioning and is weatherized.

Benefits of the Short Handle CM Series 653

Benefits of the Short Handle CM Series 653


Our customer asks: “Why did you develop a CM Series 653 ratchet lever hoist with a shorter handle? What are the advantages of the shorter handle?”

Answer:  We are continuously looking to improve existing products. The main reason why we redesigned our lever hoist with a shorter handle was to facilitate usage in confined spaces, a highly sought after feature. Other advantages offered by a shorter handle include:

  • Reduced weight of the overall hoist, making it even easier to carry and operate;
  • Allows the operator to take full advantage of the 360 degree rotating handle with less worry of obstructions;
  • Easier to fit and maneuver in confined spaces.

The 3 Most Asked Questions from our CM-ET Motor (Hoist) Schools

The 3 Most Asked Questions from our CM-ET Motor (Hoist) Schools

During our CM-ET training classes we receive many questions, especially about chain and proper lubrication. In my opinion, the chain is the most abused and neglected part of the motor. It is almost rare to find chain in the field that does not need to be lubricated unless it has just come from the factory. So here they are, your three most frequently asked questions along with our answers:

1. How do I know when the chain needs to be lubricated?

The easiest way to know if your load chain needs lubrication is by watching it as it goes into the chain bag. If it is stacking up on one side as it enters the bag, it is a sure indication that you are lacking proper lubrication.

In past years when riggers were using the old Klein type bags with the single hook connecting to the side of the hoist, the question would come up: How do I avoid the chain coming out of the bag?  When the chain is dry and it stacks up, it eventually comes out over the top of the bag.

If the chain is properly lubricated, it will flow evenly and disperse into the bag like water.

Another sure sign of a lack of lubrication is when you have a full load and you hear that “tell all” creaking sound as the chain is running over the lift wheel. What you hear is the chain actually wearing itself out by friction welding the links together and breaking that weld because there is no lube between the them. This is where you get chain wear.

2. What is the proper lubrication to use?

The oil recommended by Columbus McKinnon is 10R made by Lubriplate. There are many other brands that are available that you can get at your local hardware store. What is important is that the lube you obtain have an “EP” additive. The “EP” is short for extreme pressure. Without that additive you will not be able to keep your lubrication between the links while under a full load. Most chain saw manufacturers produce oil for their saws that contain this additive. Most bar and chain lubrications will work.

3. How do I properly lubricate the chain?

There are many ways to lube your chain but I recommend to drop your chain into a bucket and pour the lube over the pile of chain. It is important that the chain be loose and the links separated at this point. If you spray it on while the chain is hanging you might not be able to get between all the links. After adding the lube, hang it up and let the chain drip dry as long as possible and retain as much of the run off so that you can reuse it.  At this point I recommend taking some dry rags and wiping the chain down to remove as much of the excessive oil as possible. You will not be able to remove it between the links with this process, and between the links is where you want the lubrication. It is ok if the chain appears to be dry as long as the lube is between the links where it is needed.

Again, lubrication is very important and can not be neglected. Keep an eye out for dry chain.

Wire Rope Hoist Training Insights & Why Certification Matters

Wire Rope Hoist Training Insights & Why Certification Matters

Have you ever opened a Shaw-Box 700 Series wire rope hoist to see its inner workings? Do you know what the ideal preventative maintenance schedule should be on a Yale World Series, or how to properly double reeve a Cable King? The Columbus McKinnon training programs answer all these questions and a whole lot more.

In the Wire Rope Hoist Repair Certification class that I attended, each student is exposed to fully operational hoists on girders to unpowered models on accessible dollies. The class was taught by Columbus McKinnon’s training manager Peter Cooke, who has over 16 years of experience. His mix of traditional classroom instruction paired with hands-on training provides the complete setting for this certification course.

Certification is becoming more important.

When asked about the importance of training, many students replied that they were not allowed to work on a company’s hoist unless they furnished proof of certification. This seemed to be a popular response and the direction that the industry is heading.

This certification course is offered over 2 days, and gives each student an accreditation to work in the field with these hoists. In these classes, there are as many seasoned veterans as there are industry rookies which is a testament to the importance placed on certification. Everyone counts.

What material is covered during the training?

A student can expect to spend most of class time taking apart and studying the components of each hoist. Upon breakdown of the hoists, Peter teaches the proper way to inspect and replace parts, reviews wiring schematics and how to access and replace normal wear items. Over the 2 days with fellow industry technicians, there were many opportunities to discuss the tricks of the trade and best practice procedures which students can implement in their current positions.

When looking to further your expertise and gain the certifications required in many of today’s industrial settings, look no further than the Columbus McKinnon training programs. Click here to view a complete listing of training programs and to access the newest training catalog.
